通过

AddLine 方法 (Double, Double, Nullable(Double), Nullable(Double))

Constructs additional points in a geography type figure.

命名空间：  Microsoft.SqlServer.Types
程序集：  Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）

语法

声明
Public Overridable Sub AddLine ( _
    latitude As Double, _
    longitude As Double, _
    z As Nullable(Of Double), _
    m As Nullable(Of Double) _
)
用法
Dim instance As SqlGeographyBuilder
Dim latitude As Double
Dim longitude As Double
Dim z As Nullable(Of Double)
Dim m As Nullable(Of Double)

instance.AddLine(latitude, longitude, _
    z, m)

public virtual void AddLine(
    double latitude,
    double longitude,
    Nullable<double> z,
    Nullable<double> m
)

public:
virtual void AddLine(
    double latitude, 
    double longitude, 
    Nullable<double> z, 
    Nullable<double> m
)

abstract AddLine : 
        latitude:float * 
        longitude:float * 
        z:Nullable<float> * 
        m:Nullable<float> -> unit 
override AddLine : 
        latitude:float * 
        longitude:float * 
        z:Nullable<float> * 
        m:Nullable<float> -> unit 

public function AddLine(
    latitude : double, 
    longitude : double, 
    z : Nullable<double>, 
    m : Nullable<double>
)

参数

  • latitude
    类型：System. . :: . .Double
    A double that specifies the latitude of a point in a geography figure.
  • longitude
    类型：System. . :: . .Double
    A double that specifies the longitude of a point in a geography figure.

实现

IGeographySink. . :: . .AddLine(Double, Double, Nullable< (Of < <' (Double> ) > > ), Nullable< (Of < <' (Double> ) > > ))

注释

Method is used together with BeginFigure() to construct the points of a geography type figure. BeginFigure() can only construct the starting endpoint for a geography type figure. Use AddLine() to construct additional points for the figure.

Method throws a FormatException when there is invalid input.
